Your view returns rows, right? Test that first, but I
believe if you issue a "SELECT * FROM userstatus_v2", you
should get plenty of rows back.
I think the problem with your query in step 3 is that you
are trying to include the "(+)" operator in a view-using
query, and you want that operator to act as if it were part
of the view-defining query:
SELECT * FROM userstatus_v2
WHERE languageid1(+)=1;
Conceptually, by the time you execute this query, the
outer-join has already taken place. Therefore, the
languageid1 column should be either 1 or NULL. You might try
rewriting your step 3 query as follows:
SELECT * FROM userstatus_v2
WHERE languageid1=1
OR languageid1 IS NULL;
Try this. See whether it helps. I wish I had some data to
test it on myself, but I don't.
Oh, by the way, if you're running on 9i I recommend using
the newer, outer-join syntax in your view-defining query.

jon> Dear All,
jon> I have problem with view which has outer join. Could someone in this list please through some light how to accomplish Step(1) output using Step(2) and Step(3)?
jon> Isn't it "Step(1) = Step(2)+Step(3)"?
jon> Step(1) returns 24 records.
jon> Step(2)+Step(3) returns 0 records.
jon> Please enlighten me if I am wrong?
jon> STEP (1)
jon> ========
jon> SELECT T1.USERSTATUSID,
